摘要：The aim was to determine the relationship between the interthreshold area (ITA) [the area between the first and second ventilatory threshold (VT 1 and VT 2 ) for the function VO 2 /V E , load/VO 2 and load/V E ] and the traditional variables measured. Thirty-three men underwent an incremental test. The ITA was calculated: 1) as the integral defined by the area between VT 1 and VT 2 under the curves for the functions VO 2 /V E , load/VO 2 and load/V E and 2) as the simple sum of the areas described by the triangle and rectangle between the same points. The mean ITA for the function load/V E was positively correlated (p<0.01) with load at VT 2 (r=0.831) and ventilation at VT 2 (r=0.799). The mean ITA for the function VO 2 /V E was significantly greater in the cyclists than in the students. The ITA for the function load/V E differed between March and July as training progressed. The determination of the ITA is a simple method of assessing the aerobic-anaerobic transition process during incremental exercise tests.
